Abstract

A new electronic system to realize time reversal (TR) of electromagnetic waves is proposed in this paper. By utilizing the dispersion compensation approach, the system mainly contains a chirped pulse generator, a wideband multiplier, and a chirped delay line (CDL). The TR transformation is achieved by dispersing the modulated chirped pulse through a single microwave CDL. The chirped electromagnetic band gap structure with a reflected group delay slope is fabricated and used to be the CDL. It has been demonstrated by experiments that TR of triangular-wave signals in the microwave regime can be obtained through the proposed system.
